I have a question concerning the 3D drawings of a cryogenic plant. The integration of the 3D drawings of a plant with the 3D main model of a new laboratory or a new facility can be a complex work that takes a lot of time. I would like to know if the principal companies that supply medium/large helium cryogenic plants usually include in the tender the 3D drawings of the various parts of the plant or whether this is a reasonable request the customer can include in his technical specification. Does this imply added costs?

November 21, 2013The most accurate answer is that the provision of 3D drawings depends on the cryogenic plant supplier’s work process. Cryo Technologies’ cryogenic plants and equipment are nearly all custom engineered and designed. As such, new drawings are prepared for each project. We model most of our large systems and equipment (i.e. cold boxes) using Autodesk Inventor 3D software. Fabrication drawings are then produced from the 3-D model. Since we create the 3-D model as part of our design effort, there is no significant additional cost to provide our customers with 3-D files of their systems and equipment. We are able to “turn-off” layers in the model that might divulge proprietary technology and provide the customer with a files that are useful for facility arrangement and layout design.
If a system supplier performs design work in 2D only, or produces equipment from existing 2D fabrication drawings, the provision of a 3D model could be a major undertaking with associated costs.
I hope this helps.
